compute smd/ulsph_num_neighs command :h3

[Syntax:]

compute ID group-ID smd/ulsph_num_neighs :pre

ID, group-ID are documented in "compute"_compute.html command
smd/ulsph_num_neighs = style name of this compute command :ul

[Examples:]

compute 1 all smd/ulsph_num_neighs :pre

[Description:]

Define a computation that returns the number of neighbor particles
inside of the smoothing kernel radius for particles interacting via the updated Lagrangian SPH pair style.

See "this PDF guide"_USER/smd/SMD_LAMMPS_userguide.pdf to using Smooth Mach Dynamics in LAMMPS.

[Output info:]

This compute returns a per-particle vector, which can be accessed by
any command that uses per-particle values from a compute as input.  See
"Section_howto 15"_Section_howto.html#howto_15 for an overview of
LAMMPS output options.

The per-particle values will be given dimentionless, see "units"_units.html.

[Restrictions:]

This compute is part of the USER-SMD package.  It is only enabled if
LAMMPS was built with that package.  See the "Making LAMMPS"_Section_start.html#start_2
section for more info. This compute can only be used for particles which interact with the updated Lagrangian SPH pair style.

[Related commands:]

smd/tlsph_num_neighs

[Default:] none
